ABSTRACT:
A column redundancy circuit prevents a time delay in the normal and repair operations without using an additional input/output line and input/output sense-amp. In the column redundancy circuit, since a normal Y-decoder does not receive an output signal of a fuse box when a column line is enabled, a column enable operation speed increases, and a complete repair operation having no error is achieved without using an additional circuit in a repair operation.
